1, to the overall plan for centralized heat exchange station setup based on the program should be developed to avoid duplication of construction, so that the future development and current use of a close combination. Do a good job of macro-control, co-ordination of construction projects to achieve a unified layout.
2, the design of the heat station should be its indoor heat system and outdoor heat network factors are taken into account. For the pressure and design temperature should be consistent with the design requirements, heat station equipment and systems and outdoor heat network should match each other.
3, the heat exchange station should be set in the center of the heat load density is relatively large, and to make the load area as far as possible not across the main street, usually less than 1000 m heating radius.
4, should be through the technical and economic to determine the size of the heat transfer station, in order to make it easy to operate and manage, the size of the heat transfer station should be controlled as far as possible in the supply of 50,000m2 ~ 200,000m2 within the scope of the load.

1, heat exchanger heat transfer area:
2, heat exchanger operation with the management :
In the selection of heat exchanger, we mainly focus on the loss of heat exchanger, reduce the loss of the equipment itself, to alleviate the long-term operation of the depreciation, so as to extend the service life of the machinery.

1, mixed water direct connection:
(1) pump water supply pressurized water mixing heat transfer, can be installed in the secondary network of water supply mixing pump. Under the action of the control valve primary network and secondary network return water for mixing, and then pumped by the pump into the secondary network, and then its heat treatment. This system is suitable for use in the primary network and secondary network water pressure is roughly equivalent, and the primary network water supply pressure is low.
(2) pump return water pressurized water mixing heat transfer, you can install a mixing pump in the secondary network of the return pipe location. Pump in the secondary network for the return water pressurization, so that the need to implement the mixed water heat transfer water in the bypass pipe valve regulation and primary network water supply mixing heating. This way is suitable for use in a network water supply pressure is relatively high but the pressure of the secondary network back to the lower conditions.
(3) pump bypass pressurized form of water mixing heat transfer, can be installed in the primary network water supply location of electric control valves, water mixing bypass pipe in the installation of water mixing pumps, this form of installation in the high-pressure section of the primary network water supply is applicable.
